When it comes to the health of their vehicles, most Minnesota and North Dakota drivers probably don’t think about fuel injectors. That could be because they don’t understand what they do, how they function, or even what they are. At Kennedy Transmission Brake & Auto Service, we believe it’s extremely important and valuable to know and understand how your vehicle functions – even down to parts like fuel injectors. This will not only help you have a long-lasting vehicle, but it will prevent future repairs that can take a toll on your wallet.

That’s why we’re providing a guide to break down what fuel injectors are, how they function, and why it’s important to have them regularly serviced.

Fuel Injectors: The Basics

In the simplest terms, a fuel injector is a valve that delivers gas to your car or truck’s engine. The engine computer then makes sure the fuel is going to the right place, at the right time, and sending the right amount. The number of fuel injectors in your vehicle depends on the number of cylinders. The typical amount is anywhere from four to eight; some vehicles have as many as 10 or 12 cylinders.

There are two ways fuel is injected into an engine, depending on the type of system you have. First, it’s important to understand that fuel needs air to burn. With the first method, fuel is injected into a port. It then mixes with the air before it’s pulled into the cylinders. The second method directly injects fuel into the cylinders, and it mixes with air after it enters the engine. How your vehicle’s fuel system works determines your engine power and fuel economy.

Types of Fuel Injection Systems

Determining the health of your fuel injection system begins with knowing and understanding what kind you have and how it works. That’s why our technicians are specially trained in dealing with the different types of systems that are found in most vehicles throughout Minnesota and North Dakota. Here’s a basic breakdown of the types of systems we work with:

  • Single-Point Injection: Also known as a Throttle-Body Fuel Injection, this system was the first type to be used in a wide number of vehicles. It functions similarly to a carburetor and isn’t as efficient as systems that have developed since.
  • Multi-Point Injection: Also known as a port or multi-port fuel injection, this system has a different injector for each cylinder. Most modern vehicles use this type of fuel injection system today.
  • Direct Injection: Although these types of systems are more commonly found in diesel engines, these are becoming more popular in gas engines as well. As the name implies, this system injects fuel directly into the cylinders using hundreds of times the pressure of port injection systems. That means the injection process is much more precise, which helps with better fuel economy.

Keep it Clean

Keeping your fuel injectors clean is extremely important in order to keep your vehicle healthy. There are a number of factors that can lead to dirty fuel injectors, which could result in a number of problems. Things like high temperatures under your hood and the quality of gas you put in your vehicle can cause a buildup of wax, dirt, and carbon. When that happens, your fuel injectors can become partially clogged, which prevents them from delivering the proper amount of fuel at the right amount of pressure. As a result, your fuel doesn’t burn as efficiently, which can lead to bad fuel economy or complete loss of power.

It’s important these parts of your vehicle are regularly checked and cleaned because there are a lot of ways for fuel to become dirty or contaminated between the gas tank and fuel injector. If your fuel injectors aren’t kept clean, you could end up having to replace them, which ends up being very costly.

Pro Tip: Using higher quality fuel can help keep your fuel injectors cleaner for longer periods of time.
